2-5.9.1 Set STU-III ACK/NACK
It selects a protocol that requires message transfers from the near-end to be re-attempted when no
response is received from the far-end within the expected time. This selection can improve message
transfer and secure call connection reliability on a poor network. However, a very poor network
connection may extend connection times to an unacceptable degree because of repeated unsuccessful
retries. In this case, you may choose to abort the call and try for a new network connection. When the
STU-III ACK/NACK is DISABLED, the lack of a response from the far-end will cause the near-end to fail
the call.
